When a queried species is\nabsent from the mega-tree, it is grafted onto the tree using\none of two placement strategies: attachment at the basal node\nof the most closely related genus or family ('at_basal_node'),\nor random attachment below that basal node with probability\nproportional to branch length ('random_below_basal'). See Li\n(2023) for details. Multiple species\nfrom a genus not represented in the mega-tree are placed as a\npolytomy to preserve clade coherence. The package interfaces\nwith the 'megatrees' data package, which bundles or downloads\non demand curated mega-trees. Users can also provide their own\nmega-trees.", "License": "GPL-3", "Encoding": "UTF-8", "LazyData": "true", "Roxygen": "list(markdown = TRUE)", "URL": "https://daijiang.github.io/rtrees/",
